Earlier this morning, Morning Edition had an interesting discussion with Ms.Jessica Queller about her book. Pretty Is What Changes: Impossible Choices, The Breast Cancer Gene, and How I Defied My Destiny," Here is a brief summary of the book:

Eleven months after her mother succumbs to cancer, Jessica Queller has herself tested for the BRCA “breast cancer” gene mutation. The results come back positive, putting her at a terrifyingly elevated risk of developing breast cancer before the age of fifty and ovarian cancer in her lifetime. Thirty-four, unattached, and yearning for marriage and a family of her own, Queller faces an agonizing choice: a lifetime of vigilant screenings and a commitment to fight the disease when caught, or its radical alternative—a prophylactic double mastectomy that would effectively restore life to her, even as it would challenge her most closely held beliefs about body image, identity, and sexuality. . . .
